convert è = -2 to rectangular equation form

  • Pre-Cal -

    "e thing" above is supposed to be "theta"
    and theta=-2 is a polar equation

  • Pre-Cal -

    θ = -2
    This is just a straight line, along the angle θ=-2.

    Recall that the slope of the line: tanθ = sinθ/cosθ = rsinθ/rcosθ = y/x

    So, y/x = tan(-2) = 2.185

    y = 2.185x

    Makes sense, since θ is in QIII, so the line slopes up from the left.
